The invention discloses a preparation method for an alkane dehydrogenation catalyst and an application thereof. The catalyst comprises a carrier, a main catalyst and an auxiliary catalyst, wherein the carrier is an Mg-Al-O composite oxide, the auxiliary catalyst is selected from at least one of tin, indium and gallium, and the main catalyst is nickel. The preparation method comprises the steps of calcining Mg-Al-O hydrotalcite containing the main catalyst and the auxiliary catalyst in a microwave field to obtain the catalyst. The catalyst disclosed by the invention is applied in dehydrogenation reaction of cycloalkanes and paraffins, and has high selectivity of target products and relatively good reaction stability and regeneration performance. 本发明公开种烷烃脱氢催化剂的制备方法和应用。本发明的催化剂包括载体及主、助催化剂，所述载体为Mg-Al-O复合氧化物，所述助催化剂选自锡、铟及镓中的至少种；所述主催化剂为镍。其制备方法为在微波场中焙烧制得含有主、助催化剂的Mg-Al-O水滑石，得到本发明的催化剂。本发明的催化剂应用于环烷烃和链烷烃的脱氢反应，具有高的目标产物选择性和较好的反应稳定性和再生性能。
